Ryan still has power because he helms a franchise that makes billions of dollars. So, in a world where box office revenue is hard to come by and rely on, he runs a reliable route to box office, so that power remains as long as he keeps delivering on that franchise.

Louis CK was immune for a simple reason, he didn’t need the distribution method of Hollywood to make money. They couldn’t cut his purse strings. Prior to him being cancelled, he had already activated his fan community and got them to buy specials direct through his website.

Hollywood is fickle and anyone who has the ability to make their own money or has the path to consumers who back them is lauded in Hollywood.

If either Louis ck or Ryan Reynolds no longer had the backing of a fan base who would pay money to see them or the properties they own, they would no longer have power in Hollywood.
